SPECIFICATION forming part of Letters Patent No. 781,054, dated January31, 1905.

Application filed June 23, 1904. Serial No. 213,754.

To all whom, it may concern:

Be it known thatI, EDWARD H. DONAHOE, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improve ments in Stop and'Waste Cocks;and Ido hereby declare that the following is a full, clear,

and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use thesame.

This invention has reference to a new and improved stop andwaste'cock,and has for its object a backwater-flow from the outletto the waste-cockthrough the valve-ch amber therein.

The invention consists of a waste-cock hava valve-chamber, controlled bya valve, anda waste-hole leading from the outlet ofithe waste-cockintothe top of the valve-ch amber,

- waste-cock, which communicates with the chamber and the waste-holewhen the valve is closed.

Further objects and aims of the invention will be understood from thefollowing description and the drawings forming a part thereof,

Figure 1. is a vertical transverse section through the waste-cock, andFig. 2 is-a plan in cross-section through the valve-chamber and thewaste-hole as the same would appear on the line a ([of Fig. 1. r

In the drawings, 1 denotes the body of the waste-cock, having thetubular portion 2 and the laterally-extended threaded tubular por tions3 and 4. The tubular portion 2 contains within its walls a valvechamber5, and the tubular portions 3 and 4 form-an inlet to the valve-chamberand an outlet therefrom, it being understood that connection with it ishad with a supply-pipe by the waste-cock, as at 3.

lowered to engage with the seat portions 16,'

suitably arranged in the chamber of the wastecock between the inlet andthe outlet 3 and 4. The valve-stem 9 passes up through a stuflingbox 17which has a threaded connection with the upper portion of the top 6, and18 indicates suitable packing in the stuffing-box between the bodythereof and the upper portion of the top 6.

' .19 denotes an annular ring of suitable material which is carriedaround the enlarged body 11 of the stem, its periphery engaging with theinner wall of the tubular portion 2 of the waste-cock, and between thematching face of the ring 19 and the disk or flange 13 is carried aflexible ring 20 of some suitable mais arranged a waste-hole 23, leadingfrom the v outlet4 up and into the chamber 5, and in the wall of thetubularportion 2, opposite to v the opening of the waste-hole into thechamber 5, is disposed an outlet-opening 24. When the valve-stem is inits lowermost position, as seen in Fig. 1, the annular ring thereof isjust beneath the opening of the waste-holes 23 and 24 into the chamber5. 1

In the practical application'of myimproved stop and waste cockconnection is made with a supply-pipe at 3, and a faucet or some othersuitable connection is made with the cock, as

at 4. By the attachment of a valve or handwheel to the squared upper endof the valvestem the same may be raised so as to remove the washer 15from the seats 16 and. form communication between the inlet 3 and theoutlet 4. As the valve-stem is'raised the annular ring 19 will come incontact with an offset or flange 25 of the top 6, and the continuedraising thereof will cause the enlarged portion 11 of the stem to passthrough the ring, which will compress the flexible-ring 20, pressing itdown tightly over the cone-shaped portion 12 of the stem, which willcause the same to expand and impinge the inner wall of the tubularportion 2 and be held tightly over or against the upper end of thewaste-opening 23 and the outlet-opening 24 thereof,makingthesamewater-tightunderpressure. The water which will then enterthe waste-cock will pass out through the outlet-opening 4. Closing downthe stem 9 will release the pressure on the flexible ring 20 and permitit and the annular ring 19 to assume its former shape, substantially asis seen in Fig; 1, and upon the closing down of the washer 15 on thevalve-seat 16 any waste water in the pipe attached to the outlet 4:flows up through the waste-hole 23 into the chamber 5 and out throughthe opening 24, the outlet 4 and the pipe connected therewith remainingempty until the valve is again turned on.

The chamber 5 of the waste-cock being straight and smooth and the flange13 and the ring 19 being fitted closely to the walls of the said chamberand working up and down therein would remove any projection that mightadhere to the wall of the chamber, and thereby prevent any destructionto the flexible ring 20, facilitating in constructing a stop andwaste-pipe which would not easily get out of repair. The waste-hole isvery positive, as the same has a good large waterway and no smallcomplicated holes to fill up with foreign substances in the water.

Having thus fully described my invention, what 1 claim, and desire tosecure by Letters Patent of the United States, is

1. In a device of the class described, the combination of a casinghaving a chamber communicating with an inlet and an outlet, a valvestemfor controlling communication between the inlet and outlet, the sameprovided with a cone-shaped body and an annular flange, an annular ringcarried on the stem,a flexible ring between the annular ring and theflange of the stem, and a waste-opening in the wall of the casing havingcommunication with the outlet thereof and having an outlet through thechamber.

2. ln adevice of the class described,the combination of a casing havingan inlet and an outlet and a chamber communicating therewith, a waste-opening leading from the outlet through a wall of the casing to theupper portion of the chamber, and an outlet in the wall of the upperportion of the chamber opposite to the waste-opening, a stem operatingin the chamber having a cone-shaped body portion and a flange integralwith the body of the stem, a loose ring encircling the stem above thecone-shaped portion thereof and held in its normal raised position by apin passing through the stem, and a flexible ring surrounding thecone-shaped portion of the stem between the flange and ring aforesaid,adapted, when the stem is raised, to be compressed and close thewaste-opening and the outlet thereof in the chamber.

3. A stop and waste cock having a valvechamber and an inlet andoutletcommunicating therewith, a top for the chamber, a valve-stemhaving a threaded connection with the top and having its lower portionthereof cone-shaped and provided with an integral flange, a loose ringcarried around the stem above the cone portion thereof, a flexible ringon the cone portion of the stem interposed between its flange and theloose ring, a waste-opening leading from the outlet through the wall ofthe chamber and into the upper portion thereof, a waste-opening in theopposite wall of the said upper portion of the chamber, the saidwaste-openings adapted to be closed by the raising of the stem andcompressing the flexible ring by pressure of the loose ring with asuitable offset of the said chamber.

4:. In a stop and waste cock, the combination of a casing having acylindrical chamber communicating with an inlet and an outlet, avalve-stem to move the valve proper to and from the valve-seat, asecondary valve in the said chamber, composed of two rings engaging thewalls of said chamber, the lower ring integral with the valve-stem, theother ring sliding on the said stem, a flexible ring interposed betweenthe said rings and around a cone shaped body, the loose ring bearingagainst the head of the chamber when the valve proper is open, tocompress the flexible ring and swell it against the waste-openings 23and 24, the said secondary valve covering these openings when the valveproper is open, and allowing communication between these said openingsabove the secondary valve when the valve proper is closed.

In testimony whereof I aflix my signature in presence of two witnesses.
